Automation of RF and DC Labs and Development of Signal Analysis Software

The prime purpose of this project is to provide cost effective solution for the analysis of WLAN IEEE 802.11a/b/g/n signals. The software module will be able to measure the IQ constellation plot, eye diagram, spectrum mask, EVM, IQ offset and gain imbalance specifically. The second part of this project includes the automation of radio frequency (RF) and device characterization (DC) laboratory instruments at Electronics Design Centre, Department of Electronic Engineering as well as to integrate different instruments on the same front panel. We aim to interface RF and DC lab instruments through GPIB (General Purpose Interface Bus) communication tool by using LabVIEW to provide reliable and easy handling with the instruments. LabVIEW (Laboratory Virtual Instrument Engineering Workbench) is used as a major software in this project. LabVIEW supports G language (Graphical programming language) for instrumentation, data acquisition and analysis, automation and control and communication. LabVIEW is the tool of choice due to its incomparable connectivity to instruments, powerful data acquisition capabilities, natural dataflow-based graphical programming interface, scalability, versatility and overall task completeness. Industry uses GPIB interface to this day as a parallel interface for various applications in instrument control. It is widely used in instrument control because of its simple hardware interface. Since measured results obtained from laboratory instruments are to be published in conferences and journals, therefore, to achieve the IEEE compliant graphs LabVIEW will be interfaced with MATLAB.
